BaF2
Barium fluoride · VFG
Barium fluoride is a stable, wide-gap insulating crystal valued for its exceptional optical transparency.
About Barium fluoride
Barium fluoride is a robust, thermodynamically stable inorganic compound characterized by its insulating electronic nature. As a wide-gap material, it remains highly transparent across a significant portion of the electromagnetic spectrum, making it an essential component in specialized optical engineering.
Its structural reliability is underscored by its extensive representation across various materials databases. This stability allows it to function effectively in demanding environments where optical clarity and material integrity are paramount for high-precision instrumentation.
Key Properties
Cross-validated computational properties for Barium fluoride, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
